The Joye eGo features extended battery life, high durability and produces plenty of vapor with its stock Joye 510 atomizer. This unit is built with quality making it one of the best models in the market (and our favorite). A fully charged 650mAh eGo battery will last 6 or more hours for most users. If
that's not long enough, try one of our eGo XXL 1000mAh batteries for
even longer use-time. We carry a full line of parts and accessories for
the eGo. Upgrade your Joye510 today! Dimensions of eGo (standard battery, atomizer and cartridge attached): Diameter: 9/16" Length: 4-3/4"
